This is the reproducible research archive that can be used to reproduce all results and figures in the manuscript "3DCellComposer - A Versatile Pipeline Utilizing 2D Cell Segmentation Methods for 3D Cell Segmentation".
This repository can be used in two ways.
The first is to (re)generate all results in the manuscript from original images. This requires first downloading the input datasets (IMC from HuBMAP) and hiPSC from Allen Institute for Cell Science) - scripts for this purpose are available in the 'downloading' folder. The images are dowloaded into the 'data' folder, which contains an 'AICS' folder with subfolders for different image sets. Within those subfolders are lists of specific images to be downloaded. Further information on regenerating all results is provided below.
The second is to only (re)generate the figures and tables from the results. This requires downloading a large dataset that contains all of the intermediate data generated. The 'download_zenodo.py' script can be used for this purpose.
As described above, the input images must first be downloaded using download_IMC.py and download_hiPSC.py. After this, the main run_RRA.py can be used to reproduce all results. Note that this requires approximately two weeks to run on a single CPU. Note also that it requires prior installation of the packages for the various segmentation models.
The main script consists of four steps. The channels needed for segmentation are selected from the input images using code in the preprocessing folder. The individual segmentation models are run on the preprocessed images using wrappers contained in the segmentation_2D and segmentation_3D folders. Evaluation metrics are calculated from the segmentation results using code in the evaluation folder. Finally, figures are generated using the plotting folder.
The generated results must first be dowloaded using download_zenodo.py. The run_plotting.py script in the plotting folder can then be used to generate all figures and tables (see exceptions below). Alternatively, individual figures or tables can be generated with the appropriate script in the plotting folder.
The exceptions are the scripts Figures 1 and 2 generated pieces that are used outside python to generate the final figures.
The 3DCellComposer GitHub repository has the standalone version of 3DCellComposer along with examples.
